获取德国云的 Azure 访问令牌

Question

我有一个小程序在尝试获取 Azure 德国云的访问令牌时失败

public static String generateAccessToken(AzureAccount accountValue) throws MalformedURLException, InterruptedException,
                    ExecutionException, ServiceUnavailableException {
        AuthenticationContext context;
        ExecutorService service = null;
        try {
            String tenantId = accountValue.getTenant();
            String ClientID = accountValue.getClient();
            String secretKey = accountValue.getKey();
            service = Executors.newFixedThreadPool(1);
            context = new AuthenticationContext(
                                                "https://login.microsoftonline.de/" + tenantId
                                                + "/oauth2/authorize", false,
                                                service);

            ClientCredential cred = new ClientCredential(ClientID, secretKey);
            Future<AuthenticationResult> future =
                                                context.acquireToken("https://management.microsoftazure.de", cred,
                                                                     null);
            AuthenticationResult authenticationResult = future.get();
            if (authenticationResult == null) {
                throw new ServiceUnavailableException("authentication result was null");
            }
            System.out.println("Bearer " + authenticationResult.getAccessToken());
            return "Bearer " + authenticationResult.getAccessToken();
        }
        finally {
            service.shutdown();
        }
    }

该代码适用于 Azure 通用云，但适用于德国云。

这是堆栈跟踪

它似乎在寻找一些我不知道的证书文件。有人对此有任何想法吗？

还有一种方法可以使用 Azure Java SDK 获取 Azure 访问令牌，这样我就不必单独进行 REST API 调用了吗？

Answer 1

这是因为您使用的 VM 不在德国 IP 范围内。您有两个选择：

在 Azure 德国云或 AWS 法兰克福部署 VM
为了从非德国位置部署：更新您拥有的 Java SDK（我有 1.8.0_92 并更新到 1.8.0_144），这应该工作
